Configuration Options
•
Primary NTP Address:
Defines the IP address or domain name (up to 64
characters long) for the primary NTP server. (Default = undefined.)
Notes:
• In order to use domain names for web addresses, DNS parameters must first
be defined as described in Section 6.8.4.
• The Web Browser Interface includes two separate fields that are allowed to
define both an IPv4 protocol and IPv6 protocol format Primary NTP Address
and Secondary NTP Address.
• When the Primary NTP Address and Secondary NTP Address are defined via
the Text Interface, the VMR/NPS will display a prompt that instructs the user to
select IPv4 or IPv6 protocol.
• The VMR/NPS allows parameters for both IPv4 and IPv6 protocols to be
defined and saved.
•
Secondary NTP Address:
Defines the IP address or domain name (up to 64
characters long) for the secondary, fallback NTP Server. (Default = undefined.)
Notes:
• In order to use domain names for web addresses, DNS parameters must first
be defined as described in Section 6.8.4.
• The Web Browser Interface includes two separate fields that are allowed to
define both an IPv4 protocol and IPv6 protocol format Primary NTP Address
and Secondary NTP Address.
• When the Primary NTP Address and Secondary NTP Address are defined via
the Text Interface, the VMR/NPS will display a prompt that instructs the user to
select IPv4 or IPv6 protocol.
• The VMR/NPS allows parameters for both IPv4 and IPv6 protocols to be
defined and saved.
•
NTP Timeout:
The amount of time in seconds, that will elapse between each
attempt to contact the NTP server. When the initial attempt is unsuccessful, the
VMR/NPS will retry the connection four times. If neither the primary nor secondary
NTP server responds, the VMR/NPS will wait 24 hours before attempting to contact
the NTP server again. (Default = 3 Seconds.)
•
Test NTP Servers:
Allows you to ping the IP addresses or domain names defined
via the Primary and Secondary NTP Address prompts, or to ping a new address or
domain defined via the Test NTP Servers submenu in order to check that a valid IP
address or domain name has been entered.
Notes:
• In order for the Test NTP Servers feature to function, your network and/or
firewall must be configured to allow ping commands.
• In addition to the Test NTP Servers option, the /TEST command in the Text
Interface or the "Test" option in the Web Browser Interface can also be used
to ping any user defined IP address in order to make certain that the IP
address is responding.
